CARL F. BRELT'NE, OF SEATTLE, WASHINGTON.

- BOOKBINDING.

Application filed October 20, 1924. Serial No. 744,650.

This invention relates in general to the binding or rebinding of books and, more especially, to the sewing together of single sheets as distinguished from the sewing of doubled or folded sheets but is not limited thereto.

The object of my invention is to provide an improved means for efiecting the purposes above mentioned in such a manner as to produce a strong, durable and flexible book.

More specific'objects and advantages of the invention will appear inthe following description.

The invention consists in a novel procedure and adaptation of devices in the operation of sewing the sheets into sections and of assembling the sections into volume form, as will be hereinafter describe-d and claimed.

In the rebinding of books, the usual practice is to sew plurality of leaves together into sections and unite an assembly of such sections into volume form by either sewing them together on a special and expensive sewing machine, or by hand, each section being sewed to two or more attaching cords or tapes, or by hand sewing the first section to the second, the second to the third, and

so on.

In the accompanying drawing,

Figure 1 is an end elevation of an assembly of leaf-sections and end papers constituting the body portion of a book embodying my invention in its form now pre ferred by me. Figs. 2 and 3 are fragmentary perspective views of leaf-sections illustrated in Fig. 1 and shown detached. Fig. 4 is a view similar to Fig. 1 showing a modified form of the invention; and Fig. 5 is a fragmentary perspective view of one of the leaf-sections shown in Fig. 4E.

The sheets or pages 10 which are to be bound into a volume are arranged in sections as 11, 12 and 13 of a predetermined The sheets which compose the first or front section 11 of a book are sewed together in the usual manner as indicated by 14: excepting that in this instance a section includes two strips 15 and 16 or cloth to one side of each of which is applied an adhesive'gum, over the entire surface thereof. Said strips of approximately the same width (for example, onehalf inch wide) are placed on the upper and underside respectively of the assembled sheets with the surface of each strip which is not gummed in contact with the outer sheet and both are sewed together with the loose sheets. The gummed surface of the upper or front strip 15 serves by a subsequent operation to attach a folded end paper 17 for the volume and also serves .as a reinforcing protection at the sewing. The gummed surface'of the lower or back strip 16 serves likewise by a subsequent operation to attach the first section 11 to another section 12.

The sheets which constitute the second and all subsequent sections of the volume are likewise sewed in the usual manner save in the following respects. A strip 16 of gummed cloth (for example, one-half inch wide) is placed on the lower or back of each section with the non-gummed surface in contact with the last sheet, i. e. with the gummed surface down, and is sewed together with the loose sheets of each section. The gummed surface of this strip serves by a subsequent operation to attach the second section to the third and so on through the volume for each section.

Furthermore, as shown in the preferred form illustrated in Figs. 1 to 3 inclusive, as a reinforcement protection for the upper or front sheet of the second and each subsequent section I prefer to sew in at the same time a narrow strip 18 of similar gummed cloth (for example one-quarter inch wide) with its gummed surface in contact, with the upper or front sheet of the section. It is desirable that this upper or front strip 18 be narrower in width than a lower or back strip 16 to allow the latter over-lapping in the subsequent assembly of t the several sections.

It is to be understood, however, that I do not confine the invention to the use of this upper reinforcing strip 18, but submit it as preferable practice.

The lower or back strip 16 on the last section 13 of the volume serves to attach to such section a double or folded end paper 19. After attaching the end papers 17 and 19 by means of the gummed strips 15 and 16 to the first and last sections, the next step is to assemble and unite all the sections into volume form. To do this the sections are properly arranged in series and thus held in a suitable press (not shown) which engages the section assembly at the right hand unbound side thereof, and by the operator thumbing the sections apart; the upper tapes 15, or as in Fig. the upper left or binding margin, of the second and all subsequent sections are successively moistened by means of a sponge. The volume is then clamped in the press to compress the assembly of sections and are thereby l'Jon-ded adhesively and held together by means of the gumnied strips.

The sections thus bonded are then ready for trinnning, gluing, l 'Jtllltllllg, backing and the other usual steps necessary or desirable to complete a finished volume.

By reason of the gunnning oteaeh of the strips upon one side only, positioning such gunnned surfaces in the relations explained with respect to the associated sections, and by sewing the respective strips to the several sections, the St1l3S serve as flexible hinge joints to unite one section to another, and the united s ctions to the end papers.

lVhat I claim is,

'l. The method oi eonniinin individual leaves into a book, consisting in first sewing gunnned cloth strips with leaves to form sections, and then bonding together such tions into volume form 1y means 01'? the gunnned strips, substantially as described.

2. The method of coini'iinino' individual leaves into a book consisting of first sewing two guinmed cloth strips to the front and back respectively of a number of leaves to provide the front section of the book, then attaching a folded front end paper to one or said gummed strips of said front section, and then attaching the top lost of a second section to the other gulnnied strip substantially as described.

The method- Of combining; individual leaves into a book composed of leaves and end papers, and consisting in sewing the leaves with gunnned cloth strips at each side thereof to form sections, then attaching end papers to the, outer gunnned strip of the first and last sections and then moving the intermediate gunnned strips into contact to adhesiveiy unite the several ections.

l. The method of binding leaves and end papers together into book form, consisting;' in arranging leaves into sections, applying gunimed cloth-strips to each of said sections, sewing said strips and leaves together in the respective sections, moistening said strips, and then pressing the sections and end papers together to cause the gnnin'ied strips to efiect the uniting ot' the several sections and end papers.
